Abstract
Methods for manufacturing a crown for a bottle or other container has a top portion and an annular skirt that descends contiguously from the top portion. An opener assembly and an arrangement of frangible scoring lines on the crown allow for ease of opening the bottle or container. Corrugated embodiments provide material strengthening for a reduced gauge crown.

A method of manufacturing a frangible crown for a container opening, the method comprising:
- forming a top portion of the crown and an attachment portion in the top portion;
- forming an annular skirt descending from the top portion and terminating at a bottom annular edge;
- attaching an opener assembly to the top portion at the attachment portion;
- providing a frangible scoring arrangement by:
- forming a first scoring line extending from the attachment portion to the bottom edge of the skirt;
- and
- forming a curvilinear second scoring line by:
- forming an upper radial segment extending in a continuous radial direction from the attachment portion of the top portion to an annular sidewall of the skirt, and
- forming a lower annular segment extending circumferentially along the annular sidewall of the skirt from the upper radial segment to an endpoint substantially spaced from the bottom annular edge of the skirt.
